Patent CA-2253232-A1 (CA)
Inventor: PFEIFFER WALTER KARL
IPC: F24F11/00
Filed: 1997-05-20
Abstract: The invention relates to a method for programmed control of a home and building automation system (30) by means of standard programs and of sensors (40) for monitoring persons (12) room by room. In order to save energy and increase comfort, the automation system triggers actuators (52) of installations (24) or groups of installations as needed. By means of adaptive, self-teaching algorithms in the software, the systematic and stochastic behavior of one or more persons (12) in the respective room, and throughout several rooms, is stored continuously. These algorithms adapt themselves automatically, and trigger actuators (52) in combination with adjustable, deterministic algorithms. The room-oriented optimization algorithms are grouped into one algorithm, incorporating external parameters, that optimizes the automation system holistically. The individual room algorithms are adapted retroactively accordingly. The self-teaching process is controlled by signals from the presence-monitoring and activity-monitoring sensors (40). At least one sensor (40) is located in each room for presence and activity monitoring of persons (12). These sensors are linked up to presence and activity controlled closed-loop control circuits (32). These networks, preferentially of the neuronal type, with computers (34) include in their software adjustably implemented, deterministic and adaptive, self-teaching algorithms.

Title: Inter-system calling supporting inter-system soft handoff
Inventor: SUTTON TODD R
IPC: H04W36/14
Filed: 1997-05-01
Abstract: A novel and improved method and apparatus for performing an inter-system soft handoff is described. In accordance with the present invention, when a subscriber unit crosses from a first cellular system to a second cellular system, a base station controller (20) determines if sufficient network resources are available to conduct an inter-system soft handoff. If so, the base station controller (20) generates a set of signaling messages that cause a call processing resource to be allocated, and for the call to be processed at the second cellular system. The base station controller (20) then perform data-selection and data-broadcast for the call by transmitting data to the subscriber unit (28) by way of the second cellular system as well as via one or more base stations to which the base station controller (20) is directly coupled. The determination as to whether sufficient network resources are available to conduct the inter-system soft handoff is based on the type of connection that exists between the first cellular system and the second cellular system, the number of inter-system calls being conducted, and the frame offset of the call currently being processed.

Abstract: A system and method for easily directing a telephone call from a hearing caller (104) using a standard telephone (106) to a deaf, hard-of-hearing, or speech-disabled person (116) using a text telephone (114) via a telecommunications relay system (208) including a communications assistant.  The telecommunications relay system (208) is a central location where hearing callers dial a toll-free number and request a specific extension number. Based on that specific extension number, the system (208) finds an associated subscriber profile that comprises the name, actual ten-digit telephone number, and service description option of the text telephone user (116). The telephone call is then relayed to the text telephone user (116) after the dialing of the actual telephone number. The communications assistant then introduces the hearing caller (104) to the text telephone user according to the specific service description option which was selected by the text telephone user (116) when they applied for the telecommunications relay system service.

Patent CA-2270607-A1 (CA)
Inventor: BAINES STEVEN JOHN
IPC: H04B1/707
Filed: 1999-05-03
Abstract: The present invention relates to communication systems and in particular relates to the time alignment of uplink CDMA signals. A simple approach for improving the performance of received CDMA signals is discussed. This consists of aligning the timings of users' signals such that the maximum output power from a single rake finger for each user occurs simultaneously. This allows the timing to be adjusted for each user's signal independently of the others and has the effect of minimising any interference between users. The invention provides a time alignment mechanism which employs a minimum of signalling.

Inventor: SCOTTA FELICE
IPC: B65D85/38
Filed: 1997-12-02
Abstract: A package for a temperature sensitive optical component (20) includes inner (14) and outer (12) containers of low thermal conductivity plastics material, a foam insulation (18) being situated between the two containers. Within the inner container (14) are a thermally conductive plate to which the component (20), a temperature sensitive resistor, and a resistive heating element are affixed. A temperature compensating circuit (16) is located outside the inner container. The temperature sensitive resistor is part of a Wheatstone bridge at the input of the circuit (16), whereby the circuit compensates for variations in operating voltage. The output transistor of the circuit regulates the current through the resistive heating element in response to variations in the resistance of the temperature sensitive resistor. This transistor extends into the inner container (14) and is in contact with the thermally conductive plate, whereby heat from the transistor is dissipated into the plate. This maintains the temperature of the transistor substantially constant.
